Yeah, I used to be in the medical device industry. Once shipped, an update typically meant a patient needed additional surgery because of your mistake. That really emphasized the “unless absolutely necessary” part of your statement.
Not just in implantables, though implantables have that whole additional surgical risk aspect, but all medical devices have painful piles of paperwork required for each revision. They’re trying to lighten the load for “security patches” but so far it’s still a major pain. I suspect it’s the much the same in avionics and any other industry that requires documented validation against traceable requirements and all that jazz.
And the real thing, in our industry, once it is verified and validated and shipped - you don’t touch it unless absolutely necessary.
